7.4 NONMAIN Operation with MSP-GANG

The MSP-Gang Programmer (MSP-GANG) is a MSPM0/MSP430™/MSP432™ integrated circuit device programmer that programs up to eight identical MSPM0/MSP430/MSP432 Flash or FRAM devices at the same time. The MSP-Gang programmer connects to a host PC using a standard RS-232 or USB connection and provides flexible programming options that allow the user to fully customize the process.
Note: MSP-GANG is available in limited quantities and does not support newer MSPM0 devices. Please refer to the C-GANG for new, fast, gang-programming options.

MSP-GANG support programming in the NONMAIN field, follow below steps:

  1. Locate the Memory option and select All Memory.
  2. Select Secure / Protection Option to open the NONMAIN configurations window.
  3. Select NONMAIN Memory Write Enable.
  4. Modify the NONMAIN configurations directly in the MSP-GANG GUI (left side) or import configurations from the code file (right side).
  5. To erase and program the NONMAIN field, select Secure / Protect.
